Abstract

The invention belongs to the technical field of coating, and in particular relates to metal texture-simulated coating and a preparation method thereof. The metal texture-simulated coating comprises the following materials in parts by weight: 100 to 150 parts of polymer emulsion, 20 to 45 parts of sheet-like metal pigment, 10 to 25 parts of inorganic fillers, 2 to 8 parts of an antioxidant, 5 to 20parts of a toughening agent, 3 to 6 parts of a solubilizer and 1 to 5 parts of a surface treating agent, wherein the grain size of the sheet-like metal pigment is 1 to 50 microns. The metal texture-simulated coating has excellent mechanical property, high surface glossiness and metal texture.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a metal-imitating texture coating and a preparation method thereof. Background technique [0002] In recent years, with the continuous enhancement of people's awareness of environmental protection, more and more attention has been paid to coatings with metallic texture. As a general practice, the aluminum powder mentioned is actually tiny aluminum flakes, which are dispersed into the matrix resin and parallel to the substrate. Many aluminum powders are connected to each other, and the large and small particles fill each other to form a continuous metal film, covering the substrate. , showing a metallic texture. If the pearlescent pigment is added at the same time, the metallic texture of the plastic surface will be more obvious. This is because the pearlescent pigment has a special physical structure. When it is illuminated by light, it will reflect the pearlescent effect throug...
